Abstract
The present paper deals with the behavior of micro filament polypropylene fibres in concrete. Polypropylene Fibre Reinforced Concrete is an embryonic construction material which can be described as a concrete having high mechanical strength, Stiffness and durability. By utilization of Polypropylene fibres in concrete results in optimum utilization of materials and reduction in cost reduction can be achieved. An investigation on M30 grade micro filament polypropylene fibre reinforced concrete was done by addition of various percentages of micro filament polypropylene fibres i.e., 0.%, 0.25%, 0.5%, 0.75%, and 1.0%. it was found that use of micro filament polypropylene fibres up to 1% can improve the mechanical properties like compressive strength, split tensile strength, flexural strength of concrete.
